First things first, "Cthulhu" is normally pronounced /kəθulu/,, but according to Wikipedia, Lovecraft himself said that the closest you could get to the "actual" pronounciation would be "Khlûl′-hloo", with the syllable sounding like "klul" (rhymes with "full") but more guttural. I decided that I try and go more with Lovecraft's pronunciation rather than the common one, simply because Lovecraft's is more "alien" and "weird", which is exactly what I think this should sound like.

With that in mind, as well as some additional research (I found this one to be particularly handy), I ultimately strung together the following set of phonemes:

/pʰʔŋlui mglɯnaɸ χuɬu ɚʔʎɛ ɯʔgænagl ɸtaɲ/

Here's my best attempt at pronouncing that

I'd like to see how you guys would go about trying to translate that into phonetic notation. You can make it as easy or as difficult to pronounce, just as long as it roughly follows the original written sentence
